Title: Improvements in thermally operated electric switches or relays
Inventor: SHERLOCK JOHN EDWARD
IPC: H01H37/50
Filed: 1950-06-13
Abstract: 687,294. Thermal switches. BRITISH THERMOSTAT CO., Ltd. June 12, 1951 [June 13, 1950], No. 14771/50. Class 38(v) In a switch, such as that of Specification 615,948, the wire 9 is wholly or partly surrounded by a heat and electrically insulating member 11 in order to vary the response of the wire to the current passing through it. As shown, the member 11 which may be of ceramic material is supported by a clip 12 and also encloses an auxiliary heater coil 10 connected in series with the wire 9, thus enabling a greater extension of the wire to be obtained and permitting the use of smaller currents. In a modification, Fig. 3 (not.shown), the auxiliary heater is on the outside of a glass member and in a further modification, Fig. 4 (not shown), nearly all of the wire is enclosed by two glass members, without an auxiliary heating coil, so that the heating and cooling times of the wire are increased.

Title: Hydraulic buffer with closing device for doors
IPC: E05F5/02
Filed: 1932-05-30
Abstract: 386,523. Door checks and closing devices. MASTE, K., Iserlohn, Westphalia, Germany. May 30, 1932, No. 15333. [Class 65 (i).] A device which allows a door to remain at any open position without exerting any force on it but which closes the door against the action of a check when the door approaches its closed position comprises a vertical oscillating check cylinder on the door, having its pistonrod connected to one arm of a crank pivoted on the door, and a guide on the door frame arranged to engage a rubber roller on the other arm of the crank. The device is shown in its fully closed position in Fig. 1. The check cylinder f has its lower end screwed into a sleeve d pivoted on a bracket b on the door and contains a piston h pressed downward by a spring o. Ths piston-rod is pivoted at p to one arm of a crank which is pivotally mounted on the upper end of the bracket b at s and has a second arm q carrying a rubber roller r. On the top of the door frame is a guide t with which the roller r engages when the door closes. As the door opens to the position shown in Fig. 3, the piston h is raised, compressing the spring, until the piston-rod passes the axis of the pivot s, as shown, so that the parts are held in that position ; the door is then free for further opening. In closing, the door swings freely until the roller r meets the guide t, as shown, and the piston-rod is then moved over dead-centre to allow the spring to force the piston downwards and to close the door by leverage of the roller r against the guide t ; the movement is controlled by the check piston h, which has two ball valves l. The lower part of the cylinder is formed with longitudinal internal grooves w, Fig. 1, the upper ends of which are covered by the piston in the position shown. By rotating the cylinder, however, it screws out of the sleeve d and thus moves upward past the piston h, so that the tops of these grooves appear above the piston and allow fluid to pass round the piston at the end of its stroke, thus reducing the checking action and allowing the full force of the spring to act to ensure complete closing.

Abstract: 486,627. Mercury switches. BRITISH THOMSON-HOUSTON CO., Ltd. June 3, 1937, No. 15447. Contention date, June 3, 1936. [Class 38 (v)] When the container 1 is tilted more than a certain angle in any direction a circuit is closed through the mercury 6 engaging a ring contact 5 and the circuit remains closed however much further the container is tilted even though it is completely reversed. In the form shown the ring 5 is fixed to a lead 3 that passes up through a glass sheath 4 and the other lead 2 of the circuit passes more than halfway up the container so as always to be in engagement with the mercury. In a modification, Fig. 3 (not shown), the container 1 is of metal such as chrome iron alloy so as to constitute one pole of the circuit, and an insulating baffle is arranged between the ring 5 and the surface of the mercury to prevent splashing contact due to the switch being violently agitated. A little dust of silica or magnesia may be placed on the surface of the mercury to make the movement of the mercury more lively. The atmosphere in the container may be hydrogen and the contacts 2, 5 may be of tungsten or chrome iron alloy or have a platinum sheath. The platinum sheath may be confined to the tip of the lead 2.
